Objective: Despite being established as the gold standard for quantifying large artery stiffness and its additive value beyond traditional risk factors in the prognosis of hypertension, carotid-femoral pulse wave velocity (cfPWV) is not recommended for routine clinical practice in the current guidelines due, in part, to practical limitations with its measurement. A formula was recently developed (Weir-McCall et al. Hypertension. 2018;71(5):937–945) for calculation of both leftand right-side arterial path length for cfPWV determination using routinely collected clinical parameters (gender, age, weight, height, heart rate, diastolic blood pressure). However, only the right-side formula was validated. This study aimed to determine the validity of the left-side formula and whether accounting for side of cfPWV measurement would improve the agreement between formulacalculated and measured cfPWV.
